AISI 304 304L 316 316L 2b Ba 8K Mirror Cold Rolled Coil Surface treatment
| Surface finish | Characteristics and application |
| NO.2B | The surface brightness and flatness of no2B is better than no2D. then through a special surface |
| treatment to improve its mechanical properties,No2B could nearly satisfy | |
| comprehensive uses. | |
| NO.4 | Polished with abrasive belt of grit #150-#180,have better brightness with discontinuous |
| coarse stria,but thinner than No3, are used as bathtub buildings inner and external | |
| ornaments electrical appliances kitchen utensils and food processing equipment etc. | |
| Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has continuous streak | |
| HL | mainly used as buildings ornaments elevators,door of building, frontal plate etc. |
| BA | Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good |
| reflexivity like mirror,kitchen apparatus,ornament etc. |
